TABULATlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 628,176, dated July 4, 1899;, Application filetl'May 31, 1898. Serial No. 682,119. (No model.)

T0 at whom, it may concern:

Be it known that I, DORE E. FELT, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Tabulating-Machines, of which the following is a Specification.

This invention relates to the construction of calculating-machines adapted to both add numbers and to print or tabulate the numbers as they are added, together with the sums of the numbers. My endeavor therein has been to adapt such machines to use with paper in sheet or short-length form as distinguished from roll or con tinuous-length paper; also, to permit the printing upon the paper of a plurality of columns or vertical rows of numbers by providing it with a laterally-shifting paper-carriage and with mechanism adapted also to feed the paper vertically at each printing operation; also, to provide the machine with means whereby the operator may be warned when the bottom of the sheet has been reached, to the end that he may either put in a fresh sheet or shift the one already in, so as to start a fresh column of numbers thereon; also, to provide means which when the operator shifts the paper will also roll the paper back, so as to present the top of the sheet at the printingcenter, and thus enable the making of each new column of numbers of the full length permitted by the sheet. These and other features of the invention will be fully understood from i the detailed description given below when considered in connection with the accompanying drawings, forming a part thereof, in which- Figure 1 is a partial side elevation of a calculatingmachine embodying my invention and showing the part thereof to which the invention more especially relates, Fig. 2 is a longitudinal vertical section of the parts shown in Fig. 1. Fig. 3 is a partial elevation of the machine, showing the side opposite to that given in Fig. 1. Fig. 4 is a rear elevation. Fig. 5 is a detail vertical cross-section showing the paper carriage and rolls. Figs. 6, 7, and 8 are sections on the lines 6 6, 7 'Z, and S 8, respectively, of Fig. 4. Fig. 9 is a sectionon the line 9 9 of Fig. 7; and Fig. 10 is a side elevation of the ratchet-wheel shown in section in Fig. 9, looking in the direction of the arrow at line 10 10 of Fig. 9.

The machine embodies the usual numeralwheels and their operating devices-such, for

instance, as those shown in Patent No. 568,021, granted to me September 22, 1896. The wheels are not shown in the drawings; but the setting-keys are indicated at 2 2, the segment-levers for rotating the Wheels at 3, the

vibrating frame whereby 'the keys are attached to and enabled to regulate the operation of said levers at 4:, the crank supporting said frame at 5, the spring for lifting the vi brating frame at (3, the main cam at 7, Wherefrom most of the operating parts of the machine derive power, and the pivot upon which such cam oscillates at S. I have also shown at 9 an elbow-lever, at 10 a catch-lever, and

at 12 a connecting-rod, forming part of mech- 7o the operator that the ribbon should be reversed, at 20 the type-segments joined to the segment-levers by connecting-rods 21, at 22 therhammers for causing the impressions, at 23 the pawls for controlling the hammers, at

21 the levers for releasing said pawls 23, at

25 the levers connecting said levers 24 with the segment-levers, at 26 the swinging frame corresponding to frame H of my said patent, at 27 and 23 the slotted lever and crank foroperating said frame 26, and at 29 and 30 the Sl0t- 9o ted levers and cranks for operating the shafts 31, carrying the arms 32, connected by a crossbar 33, serving to lift the hammers after each operation, said shaft 31 also carrying an arm the 5 3 1 for depressing the shield 35, whereby paper is moved close to the type preparatory to printing. The totalizing-lever is shown at 36, its shaft at 37, and retracting-spring at 38, and the lever for lifting the housing 39 appears at 40.

All the parts above enumerated are either in my patent or in my pending application,

too 7 Serial No. 679,461, filed May 2, 1898, and, as will be understood from the patent, they are adapted to enable the operator to preliminarily set the type side by side necessary to print any amount coming within the capacity of the machine, whether it embraces one figure or several figures; also, to print from all the figures which are set simultaneously and at one operation; also, to enable the printing of the total of the amounts or sums added and listed at any time.

The machine is provided with a paper-carriage adapted to be moved. laterally whenever it is desired to start the printing of a fresh vertical column or row of numbers. This carriage may be made much like the paper-carriage of type-writers; but in the construction preferred by me it consists oftwo longitudinal barsA A',connected at theirends by heads A A A and A and movably supportedin stationary uprights A In this carriage are three rolls B, B, and B for operating the paper, two of which are driven and the other moves by friction. The paper is entered between the rolls B and B, and is carried around the center roli B and thence up between rolls B and B to the point of delivery.

The rolls B and B are actuated in the linespacingoperations as follows: Attached tothe lever 29' is a pawl G, the pivot O uniting which to thetlever passes through the slot 0 in the adjacent upright A. When lever 29 is actuated by the main cam, this pawl carries the ratchet-Wheel (J through one toothspace, and thereby gives motion to its carrying-shaft C, which extends from end to end of the paper-carriage and may be supported in the heads thereof. The ratchet-wheel is stationary as to location and has a spline eugagement with the shaft, so that it operates the latter in whatever position it may be, will be understood from Fig.. 9. The shaft also carries a gear 0 which meshes with an idler G and this idler actuates agear 0 upon the end of the shaft B of paper-roll l5. Shaft B carries also a second gear which meshes with a gear (1 upon the shaft B of paperroll B. This construction automatically imparts at each actuation of the main cam such an amount of rotation to the paper-rolls B and B as is necessary to move the paper vertically the extent of one line-space; but it does not interfere with the operation of the paper-rolls at will in either direction desired, inasmuch as the pawl O is self-releasing, its under surface C being adapted to cooperate with the following tooth of the ratchet in effecting such release at the end of each actuation of the wheel. The carriage maybe made of any width desired, and no change in any of the parts above described will then be needed beyond the mere lengthening of the paperrolls and the ratchet-wheel shaft C The alarm or bell, which indicates that the bottom of the sheet has been reached, is shown at D in Figs. 1, 4, 5, and 6 and is supported by means of an arm D, projecting from a rock-shaft D passing through the heads at one end of the paper-carriage and supported at its inner end in a bracket D At the inner end the shaft D carries another arm D which is placed opposite and adapted to enter a groove B in the center paper-roll B. The paper upon which the tabulating is being done is adapted to keep the arm D out of the groove so long as it covers the groove; but when the bottom of the sheet isreached, so that the groove is uncovered, the arm is impelled to enter the same by the spring D attached to arm D". (Seen at Fig. 6.) This rocks the shaft D slightly and moves the bell from the position given at Fig. 6 into the field of action of the hammer D which is attached to a vibrating arm D pivoted at D pressed upon by the spring D and lifted at each actuation of the ratchet-wheel shaft by the pivoted dog D actuated by the toothed wheel D upon said shaft. The bell is thus normally out of reach of the hammer, so that although the latter is moved at each paperfeeding operation the hell does not get within its reach until the lower edge of the paper uncovers the groove in the paper-roll.

For shifting the paper-carriage laterally after the completion of a column in order to bring a fresh portion of the paper in front of the printing-center and in readiness for the printing of another column I employ the following devices: A hand-lever E, (shown at Fig. 1,) mounted upon one end of the rock shaft E, is actuated by moving it over toward the keys in said figure. At its other end said shaft carries the crank or arm E which is connected by a rod E to an elbow-lever E stationarily pivoted at E and carrying a pawl E. A stationary bracket E projecting from one of the uprights A is provided with a stop E against which the pawl is.

pressed when the parts are in their normal position, as in Fig. 5, and this stop acts to keep the farther end of the pawl from entering the notches E of which a series are cut in one edge of one of the longitudinal members of t he paper-carriage frame. The spring E tends to force the pawl into the notches and will carry it into one of them as soon as the lever E is actuated, because such actua-' tion results in moving the pawl away from stop E When this engagement takes place, the lever IE will carry the paper-carriage to the right and until the upright to which bracket E is attached is reached by the pawl and acts as a stop to further movement. The operator now releases the hand-lever, and the retracting-spring It will return the carriageactuating parts by which the shifting has been accomplished to their starting positions. (Shown at Figs. 1, 3, and 5.) In the intervals between these shifting operations the carriage may be moved freely in either lateral direction by hand, asthe pawl E is normally out of engagement. At the same time the paper-carriage is thus shifted the paper is also moved back, so as to bring its top to the printing-center, and this operation is rendered wholly automatic by the employment of meanssuch as the following: Loosely mounted upon the shaft C and adjacent to the ratchetwheel C is a gear F, having its hub elongated at one side, as atF,such hub carryingaremovable collar F at its farther end. The gear F is compelled to rotate with the ratchet-wheel by means of the pins F secured in the disk F and extending through the gear and into the side face of the ratchet-wheel, the ratchet being recessed to receive such pins, as will be understood from Figs. 9 and 10. Gear F meshes with the gear F carryingabarrel F and supported upon a short stationary shaft F one end of which may be given a bearing in the upright A and the other end be supported in the bracket F attached at its ends to the upright. Within said barrel is a spring F which is wound up by the rotation of gear F and the'power thus stored is preserved by the pawl F engaging the ratchet-teeth F on the edge of the barrel, such pawl havinga spring F for keepingitin engagement. The pawl F is connected by a rod F with lever E and when said lever is operated the pawl is withdrawn from the barrel, as will be understood from Figs. aand 8. This leaves the spring F free to operate the dru m and through the gears F and F to rotate shaft C and thus to actuate the paper-rolls in a direction the reverse of their feeding movements. This operation should be sufficient to carry the paper to its starting position-that is to say, with its top at the printing-center. The extent of the rotation thus received from the spring may be limited in any suitable way as, for instance, by means of the stop F supported upon the hinged arm F and the spiral groove F in the side face of gear F into which said stop is entered.

To avoid the winding up of the barrel-spring when operating the paper-rolls by hand, which is a necessary operation when starting the paper into the bite of the rolls, and also to avoid all necessity for releasing the pawl F when it is desired to turn the rolls backward, as is frequently necessary, and also to avoid all danger of-the spring F operating when putting in or taking out the paper, I make the disk F movable away from the ratchet-wheel, so as to break the engagement between the ratchet and gear F, and for this purpose said disk is mounted upon asleeve F surrounding the hub F and movable along the same and provided with a projecting rim F The movement just mentioned of the sleeve is caused by the engagement with rim F of the cam end G of lever G, connected to the hinged paper-guide G by the crank G (See Figs. 2 and 9.) The guide G is located in front of the point at which the paper is put into the machine and the operator pulls its upper edge over toward the keys, and thereby brings the cam G into contact with the rim F and slides the sleeve along the hub sufficiently to draw the pins F out of the ratchet-wheel. The operator retains the guide in this bent-over position so long as depressed arm H may be employed in connection with the wheel D to regulate the step-by-step feeding movements of the paperrolls and to insure the uniformity in the extent of the different impulses.

WVhile I have described the paper as presenting its top at the printing-center when it is moved back by the backward rotation of the feed-rolls,it will be understood that I mean by this that the paper is carried back to the point from which it has been fed in the linespacing operations. This point ordinarily will be the top of the sheet; but it may be lower down on the sheet, and, in fact, at any intermediate point thereon, and hence I do not wish the claims upon this feature to be limited to means for returning the paper to-what is literally its top, especially in view of the fact that the mechanism shown by me will return the paper either to its top or to a lower plane, depending upon the location occupied by the paper at the time the line-spacing operations begin.

In order to keep the gear F normally in engagement with the ratchet-wheel G a spring J is coiled around the hub F between the collar F and the end F of the sleeve F The bracket F not only supports the shaft F but is preferably made to encircle shaft C thereby stiffening said shaft and also assisting in 'IIo keeping the gear F and ratchet-wheel C in close proximity to each other.

It will be obvious to those skilled in the art that many of the features of my invention can be changed without departing from the spirit of the invention, and hence I do not wish to be limited in my claims to the precise construction shown except in cases where the letter of the claims clearly calls for the precise construction.
